This patchset introduces the USB Host driver for i.MX28 CPU, utilising the
generic USB PHY infrastructure.
Great, many thanks!
Unfortunately, I lost the overview over the i.MXxx USB discussion ;)
Could this be used to add support for the mx53 and mx6, too? If yes,
what do you think would be needed for this?
Best regards
Dirk
P.S.: What I read from the discussion:

All recent Freescale SoC's USB controller are the same, they are mx23,
mx25, mx28, mx31, mx35, mx37, mx50, mx51, mx53, and mx6. But, the
transceiver is different between them
* mx23, mx28, mx6 (Transceiver A)
* mx25 mx31, mx35,mx37, mx50, mx51, mx53 (Transceiver B)
